POXNA how to store and draw a 2d map?
text
Body
copied!<p>I have a problem and I am not sure how to approach the solution. I need to create a 2D map editor for my XNA app., with a certain number of tiles. Say a map will be 50x100 tiles.</p> <p>I am not sure what data structure to use for the map, tiles and how to store it on the hard-drive for later loading.</p> <p>What I am thinking now is this. I will store the map in a text file like so:</p> <pre><code>//x, y, ground_type, object_type 0, 0, 1, 0 0, 1, 2, 1 </code></pre> <p>where 0=Grass, 1=River etcc for ground terrain, and 0=Nothing, 1=Wall for object types.</p> <p>Then I will have a Game Component Map class that can read that file or create a new one from scratch:</p> <pre><code>class Map : DrawableGameComponent { //These are things like grass, whater, sand... Tile ground_tiles[,]; //These are things like walls that can be destroyed Tile object_tiles[,]; public Map(Game game, String filepath){ for line in open(filepath){ //Set the x,y tile to a new tile ground_tiles[line[0], line[1]] = new Tile(line[3]) object_tiles[line[0], line[1]] = new Tile(line[4]) } } public Map(Game game, int width, int heigth){ //constructor init_map() } private void init_map(){ //initialize all the ground_tiles //to "grass" for i,j width, heigth{ ground_tiles[i,j] = new Tile(TILE.GRASS) } public override Draw(game_time){ for tile in tiles: sprite_batch.draw(tile.texture, tile.x, tile.y etc..) } </code></pre> <p>My Tile class will probably NOT be a game component. I am still not quite sure how to handle collision detection for example between a bullet originating from the player with the map object. Should that be handled by the Map class or some kind of super Manager class?</p> <p>Any hints are welcome. Thanks!</p>
